Benefits of technology

The present invention is a dual rotor wind turbine generator set that can start with a breeze, has no noise, and is highly efficient. It features a unique design that allows for simultaneous use of wind lift and resistance, resulting in increased rotation speed and overall power generation efficiency. The generator set can be started with a minimum breeze and is highly adaptable to varying wind directions. Overall, this invention offers a more effective and efficient way to harness wind energy.

Problems solved by technology

Accordingly, the wind wheel has large noise, low wind resistance, and high starting wind speed.
Therefore, the generation efficiency of the generator is low.

Abstract

A dual rotor wind turbine generator set includes an upper vertical wind wheel unit, a lower vertical wind wheel unit, a cruciform framework, and a generator located within the cruciform framework and between the upper vertical wind wheel unit and the lower vertical wind wheel unit. One of three upper blades are installed to an upper vertical shaft perpendicular to the ground. A plurality of upper semi-elliptical or semi-conical turbulence enhancing components are located at an upper leading edge of one of the upper blades. Two upper winglets are respectively installed at two ends of one of the upper blades. One of the upper blades is cut from a position at 32% upper leading edge along an upper chord thereof, as a starting point, to an upper trailing edge thereof. The wind turbine generator set has no direction and no noise and has high power generation efficiency and wind resistance.

Description

BACKGROUND OF THE PRESENT INVENTION[0001]1. Field of Invention[0002]The present invention relates to the wind power technical field, and more particularly to a vertical shaft wind turbine generator set which starts power generation via breeze.[0003]2. Description of Related Arts[0004]Most of the existing wind turbine generator use the horizontal shaft structure, which changes the wind wheel direction via the empennage, so that the front of the wind wheel directly upwind rotates to drive the permanent magnet generator to generate electricity. Accordingly, the wind wheel has large noise, low wind resistance, and high starting wind speed. The wind speed needs more than 2 m / s to start the wind wheel. Therefore, the generation efficiency of the generator is low.SUMMARY OF THE PRESENT INVENTION[0005]An object of the present invention is to provide a dual rotor wind turbine generator set which can breeze start, has no noise and high power generation efficiency.[0006]Accordingly, in order t...
